Abstract

The invention concerns a process and a device for controlled feed of alumina and halogen additives into a vat for production of aluminum by alumina electrolysis according to the Hall-Heroult technique. The alumina or the halogen additive, set aside by gravity into the storage means, is introduced into a volumetric feed regulator and dispatched under the effect of a jet of compressed air, as far as the orifice of introduction into the electrolysis vat, through a rigid system of pipes, in successive equal or unequal dosed quantities, at constant or variable time intervals. The device includes no moving piece which is subject to wear or abrasion.
